art3mis Posted July 28, 2017 Share Posted July 28, 2017 (edited) Hi In the attached short clip notice on just the left side of the statue the rim lighting is creating a ‘dancing pixels’ or animated noise effect. These are all the relevant settings. What should I try changing to eliminate these dancing pixels in the rim lighting?
